To my knowledge: The 404 error (Not Found) message is an HTTP's error response code. The error means that the client computer was able to communicate with the server..... but the server could not find the file/webpage/url which was requested by the client computer. This error is not the server error.

If u're getting this error then it means that the file is not available on ur server, or the url/path u have provided in the link is not correct. It could be possible that the directory u have created is not accessible from the web, for that u may need to change the location of the folder or u may need to check the permission settings of that folder. It should have at least "read" permission.
